A digit impulse signal, a voltage signal or the resistance signal that external device (ED) 200 exports etc. is any to reflect external device (ED) 200
The signal of state.In this way, which connector 144 is used for transmission communication signal Cmd, output device 100 can pass through connector 144
It is received from external device (ED) 200 and transmission communication signal Cmd determines output voltage Vout to DC conversion unit 142 to direct current.
It for example, is that outside is connected to Universal Serial Interface (USB) interface in the connector 144 of connection terminal 140
In the embodiment of device 200, direct current can pass through the D+ foot position on Universal Serial Interface foot position, D- foot to DC conversion unit 142
The voltage signal of position receives communication signal Cmd from external device (ED) 200, to judge the standard of supply voltage required for external device (ED) 200
Position, to adjust output voltage Vout.But not limited to this, and in part embodiment, foot position can be also communicated by others outside
Part device 200 receives communication signal Cmd, to judge supply voltage level required for external device (ED) 200, to adjust output voltage
Vout.For example, direct current can be according to communication signal Cmd to DC conversion unit 142 when external device (ED) 200 is notebook computer
Control the output voltage Vout that connection terminal 140 exports 20 volts.When external device (ED) 200 is tablet computer or smart mobile phone, directly
The output voltage that connection terminal 140 exports 12 volts or 5 volts can be controlled according to communication signal Cmd to DC conversion unit 142 by flowing
Vout。
In this way, which output device 100 still can directly turn direct current by direct current in identical DC voltage Vin
It changes unit 142 and adjusts output voltage Vout to adapt to the demand of different loads.In other words, DC link 120 is not required to setting volume
Outer signal wire transmission communication signal Cmd can only include power transit line, be used for transmission DC voltage Vin, in this way,
Output device 100 can be saved designs and manufactures cost.
It is worth noting that, direct current can be isolated power supply conversion electricity to DC conversion unit 142 in part embodiment
